The equation given to us is in the Standard form
$y = ax^2 + bx + c$ where $a = -2, b = -5 and c = 7$

The Axis of Symmetry is given by the formula $x = -(-5)/(2*(-2))$

$x = 5/4$

$color (green)( x = 5/4$ is the Axis of Symmetry of the Parabola with the equation $y=-2x^2-5x+7$

What is the axis of symmetry of the graph of y=-2x^2-5x+7 y=-2x^2-5x+7?
